i To all whom t may concern:

Beit known that I, JOHN A.' KILLIAN, a citizen of the United States,residin atl Detroit, in 'the county of Wayne, tate of Michigan, haveinvented certain new and useful Improvements in Flying-Machines; and Ido hereby declare the following to be a full, clear, and exactdescription 'of the invention, ysuch as will enable others skilled inthe art to'which it appertains to make and use the same.

The resent invention relates to new and useful' lmprovements inaeroplanes.

It is primarily the object of my invention to provide a means forincreasing the the planes. ofthe aeroplane may discharge a parachutefunction in such falling movement,'to permit a proper landing of the 1aeroplane.

A further object is to increase the general stability of the aeroplanein normal Hight,a nd to rovidefan arrangement of air engaging sur ces'wherein the structure of the aeroplane may be simplified andconsiderably strengthened.

- With the above and other objects and advantages in view, the inventionresides more particularly in th novel combination, formation andarrangement of parts hereinafter described and `particularly pointed outin the appended claims.

n the drawings:

Figure 1 is" a perspective view of the im,- proved aeroplane.

Fig. 2 is a vfront elevational view thereof.

Fig. 3 is a fragmentary sectional view at one slde of the longitudinalcentral plane.

Fig. 44 is a detail sectional view on the line 4 4 of Fig. 3, showingthe means for admitting -air through the main plane.

.Referring1 now more articul'arly to the drawings, t ere V'is provi ed amain plane 5, which 1s of nerally oblong shape and which extendsongitudinally of the machine, the `front of .this plane being taperinglyreduced to a point. This plane is bowed upwardly, longitudinallythereof, and the curvature isgradually increased toward the rear portionofthe plane whereby to exert a lifting action in the paage of the planethrough the air in a general horizontal line. Depending fromY thecentral portion of the plane and extending lon 'tudinally throughout itslen h is a sta ilizing wall 6, the

lower edge of4 which is disposed below the I side edges of the mainplane and is connected therewith by a series of tie members 7. Supportedin spaced relation above the main plane by standards 8 rising frominterrnledliate portions of said( plane is an. auxlliar plane 9 having acurvature corresponding to the curvature of the main plane and ofconsiderably lesser dimensions than the main plane whereby its edges aredlsposed inwardly of the edges thereof, this aux1l1ary plane eingsubstantially square in shape. Extendlng between the two planes andforming substantially a projection of the wall 6 is a stabilizing wall10.

In the structure thus described, the various planes and walls mutuallybrace each other to form an exceedingly simple and strong structure, andsaid lanes further co'act to afford a maximum ying eiliciency andstability inthe normal propulsion of the machine.

Formed in the intermediate portion of the main plane at the sides of thestabilizing 'wall 6 are a pairof openings 11 and these openings arenormally closed by trap doors 12 hinged to the outer edges of theopenings and controlled for opening and closing movements by rodsv13hinged to their inner. side portions and hingedly connected at theirlower ends, below the w-all 6, to a common handle rod 14.

Sus ended below the stabilizing wall is a suitab 4e car body 15, inwhich is positioned the engine 15 for driving a tractor 16 car'- ried bya shaft 17 journaled lat the lower edge of the stabilizing .wall 6extending from a point above the car body to the forward end of saidwall. The Iaero lane is provided with front and rear e evating planes`18 and 19 respectively, and `with a rudder,20.

To hold the trap doors 12 in normallyl force of wind dpressure on theplanes.

What is claimed is: 1. An aeroplane including la main supporting plane,an auxiliary supporting plane disposed above wall disposed between thetwo connected throughout its len lanes and to both the main plane, astabillzing planes,-the main plane being provided with openings at thesides of 'said wall, and means for closingl sai-d openings.

2. An aeroplane including la main sup-- porting plane, an auxiliarysupporting plane disposed above the main' plane, la stabilizing wallbetween the two planes, a stabilizing wall depending from the' mainplane, in al-inemcnt with the wall aboveit, and a body carried under themain plane. A

3. An aeroplane includinga main supporting plane, an auxiliarysupporting plane disposed above the main plane, wall between the twoyplanes4` a stabilizing wall depending from the` main plane5'a body lcarried. under the m'aiinplane, yolgienings 1n the main plane at thesfdes of the stabilizing walls and means for closing 'said openings.

4. An aeroplane including a main' supa stabilizingv side of said walland means to open and close said openings at will.

VIn testimony whereof, ll affix my signa- 35 ture', in the presence oftwo witnesses. 5
